PART 1 - INTRODUCTION
1.1 PURPOSE
A. This section is intended to define the general installation and minimum product
requirements for hydronic and steam valves.
PART 2 - GENERAL DESIGN REQUIREMENTS
2.1 GENERAL VALVE REQUIREMENTS
A. Refer to Service Index dated June 15, 2016 for valve types.
B. Valve Pressure and Temperature Ratings: Not less than indicated and as required for
system operating, maximum, and test pressures and temperatures.
C. Manual Valve Sizes: Same as upstream piping unless otherwise indicated.
D. Valve Actuator Types:
1. Gear Actuator: For quarter-turn valves with wheels NPS 6 and larger.
2. Hand wheel: Fastened to valve stem, for valves other than quarter turn.
3. Hand lever: For quarter-turn valves NPS 6 and smaller.
4. Wrench: For plug valves with square heads. Furnish Owner with 1 wrench for every
plug valve, for each size square plug-valve head.
5. Chain wheel: Device for attachment to valve hand wheel, stem, or other actuator; for
all valves installed 6 feet or higher above finished floor extend chains to an elevation
of 5 feet above finished floor. Chain shall be equipped with clasp and hook to secure
chain as not to be in the path of egress.
E. Valves in Insulated Piping: Provide stem extensions and the following features:
1. Gate Valves: With rising stem.
2. Ball Valves: With extended operating handle of non-thermal-conductive material,
and protective sleeve that allows operation of valve without breaking the vapor seal
or disturbing insulation.
3. Butterfly Valves: With extended neck.
F. Valve-End Connections:
1. Flanged: With flanges according to ASME B16.1 for iron valves.
2. Grooved: With grooves according to AWWA C606.
3. Solder Joint: With sockets according to ASME B16.18.
4. Threaded: With threads according to ASME B1.20.1.
5. Valve Bypass and Drain Connections: MSS SP-45.

G. By-pass and Drain Connections: Isolation valves shall be provide with by-passes for
Pressure Reducing Stations (PRS) and other systems as directed by Yale. Comply with
MSS SP-45 bypass and drain connections.
H. Wet Tap/ Hot Tap Valves
1. Valves shall conform to the requirements of this and other applicable university
standards.
2.2 MANUAL VALVE DESIGNATION
A. This section includes the valve identification code, and Standard used in the Service Index.

BA Ball Ball Valves
BF Butterfly Butterfly Valves
GA Gate Gate Valves
PL Plug Plug Valves
GL Globe Globe Valves
CK Check Check Valves
2.3 DESIGN DOCUMENT REQUIREMENTS
A. The design drawings shall include a riser and flow diagram and details of system
specialties for all HVAC systems. Collectively, the drawing elements shall capture and
illustrate all valve applications including: shut-off, balancing, bypass, control, direction
flow control, and drain valves.
B. The riser flow diagram shall include valve tags as identified in the university Service Index
and applicable Valve Standard.
C. Standard details, and plan view drawings shall include valves, and specialty items. Valves
and specialty items shall be tagged per university Service Index.
2.4 DESIGN SYSTEM REQUIREMENTS:
A. Where new piping connections are indicated to be connected to existing system, the
consultant shall confirm and indicate in the contract documents the location of existing
isolation valves. If there are no existing isolation valves to connect the new piping to

existing piping without requiring a pipe freeze, wet, or hot tap the consultant shall identify
the scope of work in the contract documents. The scope of work shall identify the
following
1. Location of POC
2. System and equipment interruption and coordination shutdowns.
3. Type of tie-in procedure
4. Work associated with recommissioning existing system
B. Valve flange rating shall be compliant with system working, maximum and test pressure,
per ANSI pressure classification tables.
C. Within each building there shall be a building valve to isolate the service to the building.
D. Isolation valves shall be provided at all pumps, tanks, reducing and automatic or
mechanical flow control devices, radiation, coils and heat exchangers, and at all other
apparatus requiring partial drainage of the system for periodic maintenance or inspection.
The isolation valves shall be so located as to permit removal and/or service of the isolated
equipment without draining complete or substantial portions of the system. Except where
flanged valves are used, each connection to equipment shall be made with screwed or
flanged union on the equipment side of the valve.
E. Isolation valves shall be provided at all branch takeoffs from system mains and risers and
returns to system.
F. Check valves installed in the horizontal position shall be swing checks; valves installed in
the vertical position shall be silent checks, except that all check valves in pump discharges
shall be silent checks.
G. Strainers shall have isolation valves up and down stream of strainer, to avoid draining the
entire system or hydronic circuit the strainer serves.
H. Provide blow-down valves at all strainers, and pipe to drain.
I. Risers shall have drain valves installed at the low point to permit draining of supply and
return risers without impacting other system risers. Drain valves shall have approved ball
valve type hose bibs and caps.
J. Provide balancing valves in the branch lines of water systems where hydraulic disparities
between the branches may exist.
K. Provide isolation valves of water piping leaving MER's to permit repairs of MER

equipment without draining the entire system.
L. High-performance butterfly valves shall be in the closed position during installation in the
piping systems. Leave all valves in the closed position at the completion of the installation.
2.5 MECHANICAL IDENTIFICATION REQUIREMENTS
A. Manual and control valves shall be labeled with 1-1/2" (one and one half inch) brass tags
bearing a letter to indicate the service and a number to indicate the valve. A permanent
valve chart and system schematic diagram shall show the location of all valves. Valve
Tags and schematic diagram names shall be coordinated with the final P&ID diagram.
B. Valves shall have the name of the manufacturer and the nominal size of the valve on the
body or bonnet or shown on a permanently attached plate in die-stamped letters.
2.6 INDUSTRY STANDARDS, CODE AND MANUFACTURE REQUIREMENTS
A. Valves for potable water service shall comply with the most current version NSF 61,
SDWA and shall not exceed the allowable content of lead.
B. Valves and flanges shall comply with applicable ANSI, AWWA, API, ASTM, ASME,
OSHA, and MSS requirements.
